Setuptools Gopy extension plugin

Setuptools plugin for Gopy extensions

setuptools-gopy is a plugin for setuptools to build Go Python extensions using gopy.

Usage

You can configure setuptools-gopy either through pyproject.toml or setup.py:

[build-system]
requires = ["setuptools", "setuptools-gopy"]
build-backend = "setuptools.build_meta"

[project]
name = "simple"
version = "0.0.1"

[tool.setuptools.packages]
find = { where = ["python"] }

[[tool.setuptools-gopy.ext-packages]]
# the name of the package to create (e.g. this will create hello.py, _hello.DYLIB_SUFFIX and go.py in the simple package)
name = "simple.hello"
# name of the package to build (as would be accessible through the go cli)
go_package = "github.com/LouisBrunner/setuptools-gopy/examples/simple"
# optional: select which version of Go to install (otherwise expects the system to have it installed)
go_version = "1.24.1"

from setuptools import find_packages, setup

from setuptools_gopy import GopyExtension

setup(
    name="simple",
    version="0.0.1",
    packages=find_packages(where="python"),
    package_dir={"": "python"},
    gopy_extensions=[
        GopyExtension(
            # same as above
            "simple.hello",
            "github.com/LouisBrunner/setuptools-gopy/examples/simple",
            go_version="1.24.1"
        )
    ],
)

In either case, you need to provide a target: this is the name of the Go package which should be built.

Once built, you can import Go symbols like so:

from .hello import Hello

Note that the name of the file will match the Go package that you imported.

Examples

• examples/simple shows a simple example of calling a Go function from Python
• Check gopy-ha-proton-drive for a real-life example
